1-cup milk of your choice
1/4 cup (2 ounces) chocolate of your choice
Marshmallows, for garnishing
In a mason jar, combine the milk and chocolate.
Microwave for about 1 minute and 10 seconds, or until small bubbles form at the top of the milk and the chocolate appears slightly melty.
Carefully remove (you may need to do so with a towel or oven mitt). Secure the lid on the Mason jar, and shake until the chocolate dissolves into the milk and becomes frothy.
Unscrew the cap, transfer to a mug, and top with the marshmallows.
Notes: If you don’t have a microwave, heat the milk in a small saucepan over medium heat until scalded (small bubbles form on the edge of the pan). Meanwhile, put the chocolate in the Mason jar. Pour the scalded milk over the chocolate, secure the Mason jar with a lid, and shake.
